The present invention relates to a Suction nozzle (110) for a suction device (100) for conveyance of cut waste strips (210) of a film web (200) comprising a nozzle duct (10) with a nozzle inlet (12) for suctioning the waste strips (210) and with a nozzle outlet (14) for introducing the waste strips (210) into the suction duct (130), wherein the nozzle duct (10) comprises an inlet portion (12a) adjacent to the nozzle inlet (12) and an outlet portion (14a) adjacent to the nozzle outlet (14) and between the outlet portion (14a) and the inlet portion (12a) an at least one rotation portion (16a) is assembled, whose flow cross section (20) is at least partially twisted over the run of the rotation portion (16a).
Suction nozzle for a suction device for conveyance of cut waste strips of a film web comprising a nozzle duct with a nozzle inlet for suctioning the waste strips and with a nozzle outlet for introducing the waste strips into the suction duct, wherein the nozzle duct comprises an inlet portion adjacent to the nozzle inlet and an outlet portion adjacent to the nozzle outlet and between the outlet portion and the inlet portion an at least one rotation portion is assembled, whose flow cross section is at least partially twisted over the run of the rotation portion.
Suction device for suction and conveyance of the cut waste strips of a film web, comprising a suction duct, at least a suction nozzle for a suction device for conveyance of cut waste strips of a film web comprising a nozzle duct with a nozzle inlet for suctioning the waste strips and with a nozzle outlet for introducing the waste strips into the suction duct, wherein the nozzle duct comprises an inlet portion adjacent to the nozzle inlet and an outlet portion adjacent to the nozzle outlet and between the outlet portion and the inlet portion an at least one rotation portion is assembled, whose flow cross section is at least partially twisted over the run of the rotation portion, which with its nozzle outlet is fluid communicating connected to the suction duct, and at least a blower for the generation of an air stream within the suction duct and the at least one suction nozzle.
